fuse: implement unsolicited notification
Clients always used to write only in response to read requests. To
implement poll efficiently, clients should be able to issue
unsolicited notifications. This patch implements basic notification
support.
Zero fuse_out_header.unique is now accepted and considered unsolicited
notification and the error field contains notification code. This
patch doesn't implement any actual notification.
